An inference engine is:
A)a strategy for searching the rule base in case-based reasoning.
B)the programming environment of an expert system.
C)a method of organizing expert system knowledge into chunks.
D)a strategy used to search through the rule base in an expert system by forward chaining or backward chaining.
E)a programming algorithm used to create a virtual world using VRML.

Question

Quizplus · Accepted Answer

An inference engine is a component of an expert system that uses a set of rules and reasoning to deduce logical conclusions or actions. It is used to search through the rule base in an expert system by forward chaining or backward chaining. A is incorrect because case-based reasoning and rule-based reasoning are different strategies. B is incorrect because an expert system consists of several components, including the inference engine, rule base, user interface, and knowledge base. C is incorrect because chunks are a way of representing knowledge, not organizing it. E is incorrect because VRML is a programming language used for creating 3D virtual reality environments, not an inference engine.
